AI Technical Summary

Benefits of technology

The present invention provides a coupling mechanism that is designed to be durable and secure, and can clearly indicate when the parts have been detached from each other. This design prevents accidental or unauthorized detachment of the parts, which can improve overall safety and security. Additionally, the design allows for easy identification of the detached parts, making it easier to replace or repair them.

Problems solved by technology

In addition, the second coupling element is positioned above the notch after the sheet is recovered, and the sheet is pushed outside the notch incapable of engagement with the notch so that users can clearly see that the second coupling element has been torn.
